### Architect's Scale

Posted: Sun Jul 17, 2011 10:08 pm
I am reading an architect's blueprint for the construction of a structure. The scale is 1=50. What does this mean? 1cm=50mm? Is this equivalent to 1/2" = 1'-0" on a customary scale?

1 to 50 means that the scale is fifty (50) times smaller than the actual or physical measurements regardless of the measurement unit.

Often, the blueprints explicitly identify the measurement units, e.g.: SCALE 1/8" = 1'-0", which means that one eighth (1/8 or 0.125) of each inch on the blueprint corresponds to one (1) foot of an actual object the blueprint represents.

Take another look at the your architect's blueprint to make sure that the scale reads 1=50 without any measurement unit.

If indeed, there are no measurement units listed on both sides of the 1=50 equation, then:

1cm=50cm
1/2"=50/2"=25"=2'1"

The 1 to 50 is from an Engineers scale, and not the architectural scale.
EX: 1 to 50 means 1 inch ( on the plans ) equals 50 feet, ...or 1 to
20 means 1 inch equals 20 feet. The engineers use these ratios because
of larger distances involved.

I never ever use to Architect's Scale, Can somebody explain it more. I need detailed description with its features.
